The seemingly simple operation of bagging into the counter is actually the operation of the cashier in the mall. It means that after shopping, customers put the selected goods into shopping bags, then scan the QR code and barcode, then put the goods into the cashier, and finally complete the whole checkout process. Through the operation of packing bags into the cabinet, it not only improves the convenience of customers' shopping, but also effectively prevents the wrong size of goods and forgets to check out, which greatly improves the cashier efficiency and commodity management level.

Bags are widely used in cabinets, not only in shopping malls, supermarkets, but also in cultural institutions such as libraries. For example, when borrowing books, you can use bags to put them in the cabinet, and complete the borrowing procedures by scanning the code, which can save the borrower's manpower and time cost, make borrowing books more convenient and efficient, and ensure the quality and effect of reading experience.

However, the problems and challenges corresponding to the bag entering the cabinet also follow. The biggest problem is that for some products with complex shapes, it is difficult to complete the operation of entering the cabinet without sensing the QR code. In addition, if there is not enough storage space, the bags entering the cabinet will also become bottlenecks and cannot play their due role. In view of these problems and challenges, we need the joint efforts and cooperation from all walks of life in the industry to gradually improve packaging technology and logistics capabilities and provide consumers with better shopping experience and services.
